Data Observability: A New Frontier for Data Reliability in 2024

Data observability has emerged as a critical practice for ensuring reliable, high-quality data to drive analytics and decision-making. But what exactly is data observability and how can organizations implement it? This comprehensive guide will explore:

  • The growing importance of reliable data
  • What data observability entails
  • Key pillars and how they work
  • Top use cases delivering business value
  • Best practices for implementation
  • Expert advice to start your journey

The High Costs of Poor Data Quality

In today‘s highly digital business environment, data has become a vital asset for organizations. However, poor data quality can carry significant risks. According to Gartner, poor data costs enterprises an average of $12.9 million per year. [1] Additionally:

  • 80% of analysts‘ time is spent simply finding and preparing data [2]
  • Decisions based on inaccurate data can lead to losses of 10-20% in revenue [3]

Poor data quality not only impacts the bottom line – it can also damage reputation and trust. So as organizations rely more on data-driven decisions, prioritizing reliability and accuracy is crucial. This is where data observability comes in.

What is Data Observability?

Data observability involves continuously monitoring, measuring, and analyzing data systems to ensure:

  • Reliability
  • Accuracy
  • Integrity

It provides comprehensive visibility into an organization‘s data ecosystem, including the ability to:

  • Trace data lineage from source to destination
  • Understand how data flows through pipelines
  • Track quality metrics across systems
  • Identify issues proactively

Data observability is key for master data management, governance, regulatory compliance, and more. It ensures high data quality that enables confident decision-making and meets business needs.

5 Foundational Pillars

Data observability rests on five key pillars: [4]


Analyzing data patterns, statistical distributions, and relationships enables identifying anomalies and maintaining quality. Key metrics here include consistency, uniqueness, and cardinality.


Ensuring data is current and timely provides relevant insights. Frequency of updates, refresh schedules, and latency are important freshness factors.


Monitoring data schemas and structures helps maintain integrity as transformations occur. Adhering to naming conventions and standards is critical.


Tracing data from source to destination provides transparency. Documenting data provenance and lineage enables issue diagnosis.


Managing data at scale ensures performance. Monitoring growth, utilization, and resource allocation is key.

While weightings differ, these pillars work in concert to deliver comprehensive observability.

Top 5 Business Use Cases

Here are five key ways organizations employ data observability to extract value:

1. Anomaly Detection

Continuously monitoring data quality enables detecting anomalies and inconsistencies that could lead to inaccurate analytics. Setting thresholds and leveraging automation enables early alerts on potential issues.

According to research by O’Reilly, only 32% of organizations can detect data quality issues in near real-time. [5] Data observability provides that critical capability.

2. Data Pipeline Optimization

Data observability provides visibility into pipeline performance. This allows identifying bottlenecks, gaps, and other issues leading to inefficiencies.

Monitoring data flows and metrics enables data engineers to optimize pipelines. This increases productivity, reduces costs, and drives more efficient decision-making.

3. Data Governance

Combining data observability capabilities with DataOps practices facilitates strong data governance. Features like lineage tracking, metadata management, and consistency monitoring enable:

  • Greater control and trust in data assets
  • Improved compliance with organizational data standards and policies

According to an Alation survey, 96% of respondents cited data governance as a top initiative. [6] Data observability provides the visibility to enforce it.

4. Regulatory Compliance

Data observability helps meet regulatory and compliance requirements related to data quality, control, and lineage. For example:

  • GDPR emphasizes lineage tracing to support subject data requests
  • FDA regulations require rigorous data monitoring for drug safety

Automating compliance checks via data observability reduces risk of violations while increasing efficiency.

5. Root Cause Analysis

Tracing errors back to the source facilitates corrections before reoccurrence. Data observability connects data issues to upstream systems, pipeline steps, and other root causes.

Fixing the core problem improves overall data reliability. Data observability delivers the necessary ingredients – lineage, metadata, quality metrics – for robust root cause analysis.

6 Best Practices for Implementation

Here are key tips for deploying data observability successfully:

Clearly Define Data Quality Metrics

Ensure metrics align to business needs. Track key dimensions like completeness, accuracy, uniqueness, and timeliness.

Implement Metadata Management

Centralize technical, business, and operational metadata to understand relationships. Maintain with robust data cataloging tools.

Monitor in Real-Time

Implement monitoring across the data pipeline. Ingest quality metrics into dedicated observability databases to enable real-time dashboards and workflow integration.

Map Granular Lineage

Trace datasets from source systems to data warehouse tables to reports/models. Automate via metadata collection and ML-based mapping.

Set Quality Thresholds

Establish thresholds that trigger alerts when metrics decline. For example, latency over 5 minutes or accuracy below 95%.

Foster a Data Quality Culture

Provide training and support to reinforce ownership. Have data leaders share insights from observability to demonstrate its value.

Expert Advice on Getting Started

For organizations seeking to implement data observability, leading data experts recommend:

"Start by identifying your most critical data and mapping its flow throughout systems. This enables prioritizing areas to focus observability efforts." – Joana Trindade, DataArchitect

"Leverage automation to embed observability into your workflows. Bake quality checks and monitoring directly into jobs like ETLs." – Sanjay Srivastava, Datanauts

"Get buy-in from key stakeholders by demonstrating how observability provides value – better trust in data, improved operations, reduced costs." – Suresh Peddapatnam, Trifacta

“Develop ‘service-level’ objectives for key metrics like accuracy, freshness, etc. These provide quantifiable targets for success." – Victoria Guido, Comcast

“Don’t try to monitor everything at once. Take an iterative approach based on highest priority data and use cases.” – Zen Chan, Attain

Data observability delivers immense value, but it requires cultural change and adoption across teams. With a methodical approach focused on business impact, organizations can transform data reliability and drive competitive advantage. The journey takes commitment, but the rewards merit the effort.
